I am personally of the opinion that the pain manufacturers that spend millions a year researching bottom paint are probably doing a better job of it than I would. So I just follow the directions. Every now and then I have added a few flys, a mosquito or two, and once a cockroach to the mix however.

Geez! You guys are no fun! I'm definitely going to add something to mine in the name of science and research. Maybe the placenta of a virgin, the eyes of a blind newt or a hairball from my cat "Demon".

As for the millions in research, there is actually a scientific journal by the name of "Biofouling" The journal of bioadhesion and biofilm research. Really. Biofilm

I love that the University of Texas was researching an additive made from cannabis derived THC and Cayenne. What a great use of your research dollars. Perhaps the barnacles got really hungry and ate too much cayenne?
